suffixes, many of which are still productive in the Modern Mongolic languages. From
the structural point of view, the denominal derivative suffixes are relatively uninterest-
ing, though some of them seem to have been extremely productive, such as *.tU or
*.tA.( y)i [possessive adjectival nouns], *.lA- [denominal verbs with a variety of
functions]. Among the more restricted and less commonplace categories of derivation
was gender (female sex), indicated by the denominal suffixes *.jin [female beings, from
tribal names and age expressions] and *.gcin [female animals, from colour terms].
A higher degree of grammaticalization was present in the deverbal verbs, most of
which may be understood as expressions of the category of voice, comprising the sub-
classes of passive, causative, reciprocative, cooperative, and pluritative verbs. Passives
were marked by the suffix variants *.dA- (after sonorant stems), *.tA- (after obstruent
stems), and *.g.dA- (after vowel stems); causatives by *.gA- (after sonorant stems and
stems in *r), *.kA- (after obstruent stems), and *.xA-, *.l.gA- or *.xUl- (after vowel
stems); reciprocals by */U.ldU- ; cooperatives by */U.lcA- ; and pluritatives by *.cAgA- .
The details of the actual formation of these derivatives were already in Proto-Mongolic
to some extent lexicalized. Some stems had, for instance, two alternative causatives, as
in *bayi- ‘to be’ : caus. *bayi.xul- or *bayi.lga-. There were also double causatives, as
in *gar- ‘to exit’ : *gar.ga.xul- ‘to cause to take out’.
Deverbal nouns were likewise inherently liable to be grammaticalized, and it is in
some cases difficult to draw a distinction between derivational deverbal nouns and the
inflectional category of participles (verbal nouns). The basic criteria are the degree of
productivity and verbality of the derived nominal stems. Participles may be defined as
fully productive deverbal nouns, which still function as verbal headwords in the sen-
tence. In Proto-Mongolic there were, however, many cases of lexicalized participles
which had apparently lost their verbal characteristics (or never developed them), like
*ide- ‘to eat’ : *ide.xe/n ‘food’ vs. part. imperf. *ide-xe. On the other hand, some Proto-
Mongolic and/or Common Mongolic deverbal nouns, like those in *.l (general action)
and *.mAr (potential action), function very much like participles, but are, nevertheless,
in Mongolic studies normally counted as derivational deverbal nouns.
One of the most difficult borderline cases involves the actor nouns or agentive
participles in *-g.ci or *-xA.ci. Normally listed as participles, these forms seem, indeed,
to have had a number of verbal functions in Proto-Mongolic. Many actual examples of
actor nouns are, however, better analysed as lexicalized regular nouns, like *jiru.g.ci or
*jiru.xA.ci ‘artist’, from *jiru- ‘to draw, to paint’. In most Modern Mongolic languages,
the verbal features of the actor nouns are absent or very marginal. It may also be noted
that of the two alternative suffix variants, the variant *-xA.ci is based on the imperfective
participle suffix *-xA, as in part. imperf. *jiru-xA ‘(the act of) drawing’, while the
variant *-g.ci
is a secondary derivative of the non-productive deverbal noun in *.g, as in
*jiru.g ‘picture’.
Most of the Proto-Mongolic suffixes for deverbal nouns yielded clearly nominal
formations with restricted productivity and a tendency of lexicalization. The derivatives
concerned may be characterized as various types of general action nouns, such as those
in *.dAl, *.lAng, *.lgA, *.ltA, *.li, *.m, *.mji, *.mtA, *.r. Some were, however, more
specialized and yielded nouns denoting, for instance, place of action: *.ri, *.xUri or
*.xUli; result or object of action: *.jA, *.mAg, *.ng, *.si; state or quality resulting from
action: *.xU or *.xUn, *.gAyi or *.gAr, *.mAl ; performer of action: *.xUl ; or instrument
of action: *.xUr. It is easy to see that many of these suffixes contain certain recurrent
initial elements, e.g. *.l, *.m, *.xU, which may be identified as their original primary
components, to which additional elements were added secondarily.
